Uses

The largest use for Ethylene Dichloride is in the production of Vinyl Chloride Monomer (VCM). More than half of the total VCM consumption is for construction-related applications, with pipe being the largest single product. Other products made from PVC resins include flooring, packaging film and sheet, and bottles.
